Hi

We have an IVR solution previous built on CAPI interface with Dialogic boards/SoftIP. We have now built a new version based on Diva SDK primarily because we wanted a version made in C#. Also given up a lot af control but having fewer lines and concern :-)

Most of our solution-setups rely on the IVR to put calls in to queues where they will be ringing. Therefore it is vital that a calltransfer can be completed on alerting.

Our problem is that even if we specify that transfer is to completed on alerting, it does not happen. In fact when we specify so, the call transfer never happens :-(

Some of the code:

...

private

 

 

...

DivaCall m_dcCall = null;

m_dcCall = (DivaCall) diDivaInstance.CreateCall();

m_dcCall.EnableDigitDetection = 1;

m_dcCall.TransferUseSameChannel = 1;

m_dcCall.TransferCompleteOnAlerting = 1;

m_dcCall.TransferCompleteOnProceeding = 0;

m_dcCall.TransferNoHold = 0;

m_dcCall.OnSuppServeCompleted +=

 

new _IDivaCallEvents_OnSuppServeCompletedEventHandler

(OnSuppServeCompleted);

...

private

 

 

void BlindTransfer(string sReturnParam)

{

 

   DivaResultCodes drcResult = m_dcCall.BlindCallTransfer(sReturnParam, 70);

   if (drcResult != DivaResultCodes.DivaResultSuccess)

   {

      m_dcCall.Disconnect();

   }

}

...

The first call goes on hold. Nothing is signaled to the application before the transfer-destination answers the call and hangup again (-because there is no-one in the other end). Then the 'OnSuppServeCompleted' method is called due to the 'OnSuppServeCompleted' event from the DivaCall object 'm_dcCall'. The parameter of the event (int bSuccess) is 0 (==false). The first call is still on hold and stays there until we retrieve it.

The calltransfer works out fine if we remove the 'TransferCompleteOnAlerting' and the transfer-destination answers the call.

Drivers and SDK version:

Can anyone tell us if we are doing something wrong or if there is a known bug somewhere?

Thanks.

If you can take the SDK trace, and at the same time record the SIP flow with Wireshark then it should be possible to see what is going wrong.

Hi Martyn

By 'SDK Trace', do you mean the trace I can make with the Dialogic Diva Diagnostics? If not, can you then specify how to make it?

Thanks.

No, there's a specific trace tool that records the conversation between your app and the SDK.  You can see the instructions here.

Hi Martyn

I made a SDK trace. Unfortunately I don't know how to interpret it. Can you help me to understand what to look for and possibly tell me what I do wrong. Thanks.

The scenario:

975 calls IVR (944) who wants to transfer the call to 955.

The Wireshark trace shows normal SIP-signaling as I would expect it to be:

 

Here is the part where I am lost. Below I have put in a part of the quite comprehensive SDK trace file starting from the point where my application have called 'BlindCallTransfer("955",  70)':

There is a transfercompleted event, so the SDK thinks the transfer has completed. When you say that the transfer isn't working, do you mean that the calls are not connected at the end of the procedure, or is it something about the way you are measuring the success of the operation in the application?

Can you attach the actual wireshark trace, I can't see much from a screen shot?

An alternative to using BlindTransfer would be to use supervised call transfer, which will give you more control over the operation.

WST_BlindTransfer_Alerting20090626.zip

Hi Martyn

In the scenario 955 hangs up at 08:57:41 because there is no-one at the other end (just an IVR line that should transfer the call). I only see something about a 'TransferInitiated' before that point. The calls are never connected. My application will just try to transfer again until 975 hangs up. 975 is just on hold until hang up.

I do miss a REFER request in the Wireshark trace to transfer the call.

I have attached the Wireshark trace in a zip-file as the pcap file extension was not allowed.

I have considered Supervised Call Transfer but I am a bit uncertain how it works in regards to have 2 Call objects and what I should do with the second call before calling the 'SetupSupervisedCallTransfer' method. Besides it looked super easy just calling one method to make a blind transfer :-)

Thanks.

Right, I see the HOLD in the wireshark trace, but no REFER.  Let me check on something...

It's not really clear which component is not doing its job.  We'll need to collect some more trace information (CAPI and SIP service).  Please open a problem with the contact center, and they'll give you further instruction.
